v Applicatiog filed March 30, 1903. Serial No. 150,278.

To all whom it may concern: I

Be it known that I, TREVELYAN SHARP, a subject of the King of GreatBritain and Ireland, residing at Manchester, in the county of 5Lancaster, England, have invented'new and useful lmsprovements inApparatus for Compressing crap Metal, of which the following is aspecification. I

This invention relates to apparatus for compressing scrap metal intoblocks or slabs; and its primary object is the reduction of the numberof mine necessary in other machines constructed for the like purpose. Bythese im rovements the general construction of suc apparatus is greatlysimplified, while its efficiency is increased.

The improved apparatus consists, essentially, in a cast-iron box havingthree fixed walls, one reciprocable wall, and a slide-lid. Two rams onlyare required, as compared with four or five rams in existing app aratusahorizontal ram for compressing the material into a smaller compass bypushing the recip rocable wall forward and a vertical ram'for 1 behereinafter which motion is given by the hydraulic ram 0. The slidecover or lid dis movable to and fro in the guide-rails d and can bemoved in one direction, so as to inclose the box-cavit and in the otherdirection, so as to complete y uncover it. As shown by the drawings, itasses through a slot in the upper art of the back wall and may beprevented om rising when pressure is applied on the tops of the walls.Its motion can be effected manually or mechanically. The in.-;

- ner face of the wall band of the back wallare so constructed, as shownby Fig. 2, that when the wall I) is pushed into the box to the limit ofits travel there is inclosed between the two parts the-rectangular space6, i "sides of the box, into which the metal is finally compressed. Toaccomplish thisand metal inwardly in the it being jammed beby internalflanges box, and thus prevent further compressing the material fromabove. The accompanying drawings illustrate .my

' pression of the diagonal to the tween the ram or movable wall I) andthe adjacent walls of the box, the face of the ram 1) is inclineddiagonally across the box or press for the greater part of its length,and where it forms an acute angle with the box a reentering lip or shelfis disposed to also direct the scra inward at that edge. The end wall ofthe ox and two of thefaces of the verticallymoving ram are disposedarallel to the inclined ace of the ram 6. n Fig. 2 a part of theslide-cover dis shown to be broken away, so as to disclose thisrectangular space, which is indicated by broken section-lines. Over thispart of the box the vertical ram is arranged, the horizontal ram beingarranged at the back or outer side of the wall I).

When the apparatus is to be used, the box is fully 0 en and both ramswithdrawn. The box is led with the scrap metal and the slide-cover dispushed over the box into corrtact with the wall 1), against which it isshaped to fit. The hydraulic ram 0 is now put into action and graduallyushes forward and compresses the'mass oi metal, at the same time pushingwith it the cover (1, which prevents the rising of the metal. When theram c has arrived at the limit of its stroke, the

slide-cover is withdrawn from over the space e, into which the whole ofthe metal has now been compressed and becomes SIJiPPOItBd by theuide-rails of the frame f. he vertical T811115), which has a head ofrectangular crosssection adapted to fit into-the s ace e, is now causedto descend and to complete the commetal in that space. The

rams are then withdrawn and the block of compressed metal is removed,after which the operation is repeated with a fresh supply of metal.

The cylinder 9 of the ram h in theconstruction illustrated is carried onthe cross-head s, which is supported by four vertical columns. Thecylinder 0 of the ram 0 is fixed on a bed which is bolted to the box aat its front end ,and is additionally secured thereto by means of a lugn on the cylinder, a cross-rail m at the back of the lug, and two straps0 0, bolted to the box a.

Below the box there is a cavity h through which water may be circulatedto keep the box cool when in use. may be '5, upon the screw-threadedouter end of the check-rod 11, whose inner end is securedto the ram 0.

The travl of the ram 0 limited by adjustment of screw-nuts To avoidconfusion in the. drawings, the

water-service for the hydraulic rams has been omitted, its constructionand arran ement being well known and understood. he return strokes ofthe rams may be made under water-pressure or under the influence of theweights w w, as is also well understood.

Although I have described pressure as being applied to the metal byhydraulic rams, I desire it to be understood that I do not limit myselfto this means, since other'means for applying the requisite pressure,such as screws, may be used.

What I do claim as my invention, and desire to secure by Letters Patent,isg 1. An apparatus for com ressing scra metal consisting of a boxhaving three fixe walls, a sliding cover, a movable wall or ram whichengages with and moves the sliding cover with it during thecompression-stroke of the ram, and a second ram at right angles to thefirst and .operating to com lete the compression of the scrap,substantia ly as set forth.

2. In apparatus for compressing scrap metal, a box having a slidingcover and three fixed sides, in combination with a ram to compress thescrap under the cover, said ram engaging with the sliding cover andmovin it vsn'th it during the compression-stroke, and a second rammoving at right angles to the first to further compress the scrap afterthe cover has been withdrawn from the box, the faces of the rams and theinner face of the end of the box formin a diagonal chamber in the end ofthe box, suistantially as described.

3. In an apparatus for compressing scrap metal, the combination of acompression-box having an inclined face at its inner end, a slidincover, a main ram havin an inclined face a utting against one end ofsaid sliding cover, and a secondary or final ram to complete thecompression of the scrap, the faces of the two rams and the inclinedface at the inner end of the compression-box forming a diagonal chamberin the end of said box.

4. In apparatus in which scrap metal is compressed in a box by two ramshaving their axes at ri ht angles, the combination with the box an withthe horizontal ram, of a sliding cover which is engaged by'and moveswith the horizontal ram durmg the compression-stroke and under whichcompression is effected.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
